One thing people could do who feed raw is use a sheet like I do, I just put down a big sheet in the kitchen, no food that the dogs have leaves the sheet and I supervise them while they eat, they are so used to the sheet now that they don't even attempt to take food away from it. When they are done it goes straight in the wash. I clean surfaces and hands when I prepare food for them as I do in the preparation of our own food.
